An image processor includes: a receiving unit that receives an input of image data in a first color space; a first color conversion unit that performs color conversion of the image data received by the receiving unit to image data formed of a first combination of color components in a second color space; a second color conversion unit that performs color conversion of the image data received by the receiving unit to image data formed of a second combination of color components in the second color space, the second combination being different from the first combination; and an image generating unit that generates an image based on at least the image data generated by the first and second color conversion units. Each of the first and second combinations includes a smaller number of color components than the number of color materials to be used in formation of an image.

The color signal converting apparatus is provided with: a color signal receiving unit that receives input of first color signals; and a converting unit that performs a conversion of the first color signals received by the color signal receiving unit, into second color signals. The converting unit performs the conversion to make a total sum of color component values of each of the second color signals equal to or smaller than an upper limit value set for each of the second color signals.
摘要:
An image processing apparatus for simulating a print output of a printing machine. The image processing apparatus firstly acquires color value information for converting color value information of image data so that a color reproduced on one surface of a recording medium by the printing machine based on the color value information is reproduced as an output. The image processing apparatus secondly acquires show-through color profile information for converting the color value information so that the color reproduced on the one surface by the printing machine as seen from the other surface is reproduced. The image processing apparatus then generates image data formed by composing first image data obtained by converting the color value information based on the color profile information, with second image data obtained by converting the color value information based on the show-through color profile information and by inverting the converted color value information horizontally or vertically.
